CAR-TRUCK FRAME Specification of Letters Patent.

Patented July 23, 1907.

Original application filed February 14, 1896, Serial No. 579,234. Divided and this application filed October 18, 1904.

Serial No. 228,256.

To all whom it may concern:

Be it known that we, RANSOM G. WRIGHT and FRANK E. STEBBINS, citizens of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania,- and Washington, District of Columbia, respectively, have invented certain new and useful Improvements in Car-Truck Frames, of which the following is a specification.

The invention relates to car trucks and especially to the frames thereof, our object being the production of a metallic frame which can be manufactured cheaply,

and repaired when necessary in the ordinary car shop;

which shall be strong and durable and have the pedestals separately fashioned and secured to the ends of the side pieces so that should occasion demand they can be removed and new one substituted; which shall have the pedestals made in such shape that they may receive and rest upon springs supported by the journal boxes, thus cushioning the entire frame; and which, withal, shall constitute improved means for performing the requisite functions of a frame adapted to support and carry heavy cars and loads. I

With these main ends in view our invention consists in certain novelties of construction, formation, and combinations of parts as hereinafter set forth and claimed.

The accompanying drawings illustrate two examples of the physical embodiment of our invention constructed according to the best modes we have so far devised for the practical application of the principle.

Figure 1 is a side view of a car truck embodying our improvements. Fig. 2 is a one half top plan view of Fig. 1, the other half being of similar construction is not shown. Fig. 3 is an enlarged side view of one of the four ends of the frame shown in Fig. 1. Fig. 4 is a top plan view of Fig. 3. Fig. 5 is a side view of an end of a frame showing another example of pedestal construction and attachment. view of Fig. 5. Fig. 7 shows the section of a composite side piece which may be substituted for the side pieces shown in other views.

Referring to the several figures, the numeral 1 desig nates the side pieces of the frame consisting of flanged metallic beams, in this instance of channel form, rolled or pressed to shape, the web and flange or flanges of each beam being provided with suitable holes to receive rivets; 2, the transoms, in this instance of metallic channel beams rolled or pressed to shape,-pr0vided with suitably spaced holes in their webs and flanges; 3, connection angles which secure the webs of the transoms to the webs of the side pieces by rivets passed through the several parts, as shown; l, top gusset plates, and 5 bottom gusset plates, each being riveted to the Fig. 6 is a top plan flanges of the transoms and side pieces; 4, one of the tie pieces which unite the webs of the transoms by means of rivets passed through the several elements; and 5 is a top tie plate uniting the centers of the transsoms and riveted in place.

The first example of separate pedestal is made substantially as follows: A rolled steel plate is cut to the required shape, heated and pressed between dies or forged under a hammer so as to have a flange 6 extending around the outer edge from the point 7 to the point 7, and also an inner flange of a .[1 shape to receive and guide a journal box, the said inner flange embracing a horizontal portion 8 and perpendicular portions 9 and 10. The outer, lower end of flange 6 and the lower end of flange 10, as well as the lower end of flange 9, are perforated to receive a tie bolt 11. which passes through a spacing piece or thimble 12, as shown. 1 A nut secures the bolt in place. Between the flange 6 and flange 8 is located a filling or strengthening plate 13 provided with a perforated flange 14, the said plate 13 being secured in position by the rivets 15 passed through the steel plate and the web of the strengthening plate as clearly illustrated. The pedestal thus fashioned is placed upon the end of a side piece and fastened by the two rows of rivets 16, and rivets 17 passed through the upper flange of the side piece and the flange 14 of the strengthening plate.

The second example of pedestal construction is made in a manner similar to the first. It is fashioned so as to have the continuous flange (3, extending from the point 7 around to 7 and the strengthening plate 13 is applied in the same way to the head of the pedestal as is shown and described in the first example. The I1 shaped flange embracing the parts 8, 9 and 10 is, however, not made integral with the steel plate as in the first example, but consists of the flange of an angle iron bent or cast to a ll shape and with the web of said angle iron secured by rivets 18 to the edge of the opening for the journal box cut from the steel or'base plate. The flanges at the lower ends of the angle iron are perforated to receive the tie bolt, and an angular piece of metal 19 maybe riveted to the lower flange of the side piece by rivets 20, and the free leg perforated to-receive the tie bolt, thus rigidly anchoring the inner end of the said bolt. may be bent outwardly and secured to the upper flange of the side piece by a rivet 21, as shown. In attaching this pedestal to the end of a side piece the outer row of rivets 16 will pass through the web of the angle iron, the steel plate, and the web of the side piece, as is obvious.

It will be observed that in both the examples of pedestals sections through the head and outer jaw are chan- If desired, the upper end of flange 6 nel-shaped; that the strengthening plate 13 reinforces the head of'the pedestal; that the rivets which secure the pedestal to the end of a side piece pass through both the pedestal and end of a side piece and hold the surfaces in close frictional contact; and that the pedestals are relatively of light weight. Wearing shoes may obviously be added to these pedestals when desired.

In Figs. 1, 2, 3 and 4c the forged or wrought metal pedestal is shown applied to the plain web surface of the end of a channel side piece, the flanges thereof being turned outwardly, or, in other words, the pedestals are applied to the back end surfaces of the channels.

In Figs. 5 and 6 the channel side piece has its flanges extended inwardly and the pedestal is applied to the front end surface. Either side piece may be turned end for end when secured to the transom ends. Fig. 7- shows two bulb irons which may be substituted for the channel side piece whenever desired. Two parallel angle irons or two parallel channel irons may also be used, constituting a composite flanged side piece.

In Figs. 1 and 2 the numeral 22 designates the axles; 23, the wheels; 24, the journal boxes with recesses in their sides; 25, the removable spring caps; and 26 the helical springs interposed between the journal boxes and the caps, which latter bear against the flanges S of the pedestals, thus cushioning the entire frame.

From the foregoing description taken in connection with the drawings it becomes obvious that We have produced a car truck frame which fulfils all the conditions set forth as the purpose of our invention, and which possesses other characteristics of construction constituting the same a superior means for the purposes intended.

While we have shown only two examples of the physical embodiment of the invention, we do not thereby intend to limit its scope to such specific constructions, inasmuch as the principle may be embodied in other forms and constructions and by other modes without constituting substantial departures.
